This invention pertains to bobbin winding machines generally and more especially is concerned with bobbin handling devices therefor.

The primary object of the invention is to provide an automatic bobbin handling mechanism for machines of the character described which will so perform the functions of doffing and of storing a wound bobbin that the machine may be employed to Wind delicate yarns, such as a fine cotton, nylon or rayon.

More specifically stated, the invention aims to provide a doffing mechanism which will receive a wound bobbin from the Winding spindle of a winding machine and deliver the same to a storage device, such as a slowly moving conveyor, without subjecting the material wound on the bobbin to any surface which will injure it.

Another object of the invention is to associate a doffing mechanism with a donning device in a manner such that the two operations may be performed with but a single transfer mechanism.

A further object of the invention is to provide an improved clamping and shearing device for a bobbin winding machine which is operable in timed relation with its doffing mechanism.

The objects of the invention thus generally stated, together with other and ancillary advantages, are attained by the construction and arrangement shown by way of illustration in the accompanying drawings forming a part hereof, in which:

In carrying out my invention, I provide a traveling storage medium, preferably in the form of an endless chain conveyer equipped with individual supports to which the wound bobbins may be successively transferred upon release from the winding mechanism. The conveyor is advanced with a step-by-step motion to present th individual supports successively into position for the reception of wound bobbins from a transfer mechanism timed with respect to the winding mechanism and the conveyor. While being wound the bobbins are advantageously supported forfrotation on a horizontal axis and the storage conveyer is vertically disposed on one side of such axis, while on the other side, is an empty bobbin supply means including a magazine from which empty bobbins may be delivered one by oneto the Winding mechanism. With this arrangement in view, the bobbin transfer mechanism is especially constructed for the performance of theadditional function of taking an empty bobbin from the magazine and delivering the same to the Winding mechanism simultaneously with the transfer of a wound bobbin to the conveyer. In its present illustrative embodiment, the invention is shown as being applied to a machine of the type which is composed of a plurality of units arranged side-by-side in a suitable supporting framework and having a common driving and control mechanism. In general, each unit comprises (Figs. 1 and 2) a winding mechanism A including a horizontally disposed spindle, an empty bobbin supply mechanism B on one side of the spindle, a storage mechanism 0 on the other side equipped with individual bobbin supports, and a transfer mechanism D designed to operate between the empty bobbin supply mechanism,

the winding spindle and the storage mechanism and including two receptacles, one for taking an empty bobbin from the magazine and placing it in position to be clamped to the spindle and the 3 other for receiving a wound bobbin from the spindle and transferring the same to the storage mechanism.

The empty bobbin supply means B comprises, as herein shown, an upright magazine l arranged to support a vertical stack of empty bobbins. At its lower end it is equipped with means generally designated H for releasing empty bobbins one at a time to the transfer mechanism D, as hereinafter more full set forth.

The bobbin winding mechanism forms per se no part of the present invention. As shown, it is of the type disclosed in copendingapplication, Serial Number 450,129, filed July 8, 1942, by Brooks Marcellus, now Patent No. 2,409,639, issued October 22, 1946. spindle l2 equipped with a chuck I2, for coaction In brief, it comprises a of a bobbin. In order that the fingers 29 and 3! may not be fouled (see Fig. 5) When the carrier arm 25 is returned to its retracted position, the cradle 26 is yieldably attached to the arm by means of a pin 32 about which it is free to move. It is held in its normal position by a tension spring 33 which urges a lug 34 forming a part of the bracket against a stop 35.

For receiving wound bobbins onto the transfer mechanism the receptacle must be shaped to hold a bobbin which is dropped from the chuck IF and for this purpose the trough 21 is employed. Like the cradle 26,-the trough Z'Lisyieldably attached to the arm 25 since it is desired to have it move substantially horizontally to its discharge position forwardly of the conveyer [6. In

7 this case, an arm 3'! which supports the trough is with a centering slide E3 to rotatively support an 3 empty bobbin l5 upon which the bobbin filling is wound. In the present instance,themachine-is intended for use in producing filling wound bobbins known as oops or pirns. Accordingly, the

winding mechanism also includes a unidirectionally rotating traversing cam sleeve I4 encircling parallel with but offset rearwardly of the bobbins as they are being wound '(see Fig. 2). I

The driving and control mechanism common to the several winding units is generally designated by the numeral 20 (Fig; 1). It provides a means for operating the bobbin transfer mechanisms, the shearing devices, thestorage'conveyers and other instrumentalities of all units. A mechanism of thistype is fully described insaid Patent No. 2,409,639. Since it forms per se no part of the present invention, it will not be treated in detail here. In brief, it comprises a main cam shaft 2| which carries separate camsfor driving each of the various instrumentalities mentioned above. This shaft in turn is driven'by means of a motor 22 operating through a drive 23, a shaft 24 for driving said cam shaft and suitable gearing, not shown. The cam shaft 2 Lin addition to furnishing power, also controls the timing of the various operations such as donning, do'fhng, etc. with respectto that of winding as described in said copending application.

Referring nowv to Figs. 4 and 5, the bobbin transfer mechanism comprises in the present preferred embodiment of the invention, a pivotally mounted upright carrier arm 25 to which are attached.- a cradle 25 and a trough 21. The form taken by these two bobbin receiving receptacles and their mode of attachment to the arm 25 is dictated largely b the manner inwhich they function and by the fact that they are both mounted on the same arm.

The first receptacle must support and hold an empty 'bobbin'for aperiod of time and then release it after the 'samehasb'e'en' clamped in winding position. To do this with aminimum numberof working parts; the cradle Zt'is employed. In the presentenibodiment, it takes the form of a U-shaped bracket whose arms are bifurcated to form' receiving fingers 28- 29 and 30- 3! (Fig. '7) respectively for the tip and head attached tothe-arm 25 by means of a bracket 38. The arm 31 is thus permitted to pivot about a T'po'int'BBQand under the action of a tension spring 40, a rollerdlcarried on a movable base plate 42 (Fig. 6) of trough 21 is held against a fixed guide -bracketflii. -Thus, asthe arm 25 moves from its position illustrated in Fig. 4 to the one shown in Fig. 5, the roller ll moves along the track 43 into a position in front of the conveyer 16 as shown. Here, the level er the guide -bracket 43' establishes a datum to which eachof thepins- I! maybe indexed by means associated with the conveyer later to'bedescribed. "As thearm 25 returns to itsnormal position, it operates t'heescapement I l'. The latteris in theform of a bar pivotally supported at its upper end- '(Fig) 1) and having -a laterally projecting finger Ha, the member being urgedby a torsionspring- Hb in a directiontocarry the finger I la toward the magazine. -Wheri the arm 38 is moved into the-position sh'ownin- Fig.4, the escapement member is retracted against the action of the spring llb, causing it to release the bobbin from the magazine intothe cradle 26, the

remaining bobbins being 'supportedby the bobbin thus released. :As' the released bobbin is moved out from under the'next lowermost bobbin in the initial portion of the ensuingdon'ning stroke-of I the arm 38, the finger l Iais carried by the spring lib {into position beneath said next lowermost bobbin soas to supportthe stackof bobbins in the magazine until the--arm"returnsand withdraws the finger Ha for the release into the cradle of the next'bobbin.

In addition to being "movable transversely with respect 'to' the-spindle axis, the trough 21 is also mounted for movement-parallel thereto by a special mechanism which causes 'the discharge of a bobbin from the trough onto the conveyer. To provide'for this "mobility, the trough 21 is attached to the movable base plate 42 which in turn slides in grooves or ways Mchanneled in the arm 31.

Since the express function'of the transfer 'mechanism is to transfer bobbins from fixed points to fixed points, it is obvious that itsmovement between these points must'be controlled in I0 and similar regulation of the stop 41 positions it accurately before the chuck I2 for clockwise rotation. In the first of these positions, the trough 21 rests under the winding spindle, and in the second it occupies what is termed as its delivery position. The horizontal alignment of the trough 21 with the conveyer I6 is made by proper location of the latter, the horizontal distance between the bobbin axes of the cradle and the trough being fixed by their selected dimensions.

The movement of thearm 25 between the above established limits is effected by means of an arm 49 (one for each unit) also pivoted on the shaft (Fig. 2) and operatively connected to the arm 25 through the shaft 45 and an overload detent 50. The arm 49 is connected to a reciprocatory bar 5| which extends longitudinally of the machine so as to serve all units, and is actuated in a horizontal plane by a barrel cam 52 in the common drive and control mechanism 20. This cam is mounted on the main cam shaft 2| and cooperates with a cam follower 53 which is pivoted at 54 and connected to the bar 5| by a link 55. As the cam 52 is rotated, the follower 53 is cammed inthe groove 56 and the bar 5| is rocked to move the bobbin transfer mechanism of all units together.

Closely associated with the bobbin transfer device D just described, is a mechanism 51 controlling both the movement of the centering slide l3 and also the ejection of a wound bobbin from the trough for delivery to the storage chain. It comprises a cam operated pinion 58 (Fig. 2) which meshes with a rack 59 on the centering slide l3 to move the latter toward and away from the spindle l2 during the process of mounting and releasing a bobbin. Moreover, it includes a plunger 6|] for shifting the trough 21 rearwardly toward the conveyer l6 to discharge a wound bobbin 6| onto a pin I! of the storage chain.

Like the previously described instrwnentalities, the slide and plunger mechanism 51 is actuated from the common driving and control mechanism 20. Here (Figs. 1 and 2) a cam 62 on the main cam shaft 2| controls the operation of the centering slide f3 through a bell crank 63 which is pivoted at 64 and carries a cam follower 65 on one end and a gear segment 66 on the other. The segment 66 meshes with and drives a gear 61 (Fig. 1) keyed to the extreme end of a longitudinally extending shaft 68 on which gears 58 (one for each unit) are also fixedly attached.

The bobbin ejecting plungers 6|] of the several units are also actuated by the cam 62. To this end, the gear 6! meshes with a gear 69 fast on a rock shaft '10 parallel with the shaft 68 and having keyed thereto a toggle arm (Fig. 6). This toggle arm is connected by a second toggle arm 12 to a crank 13 fixed on a rock shaft 14 extending lengthwise of the machine and having attached thereto by means of overload detents 14 a series of plunger arms 15 (one for each unit). Each arm 15 is connected to its plunger by a pin-and-slot connection 16 which operates the plunger to move the trough 21 toward the conveyor I6.

Since the bobbin transfer mechanism of which the trough 27 is a part, moves transversely relative to the motion of the plungers 60 and independently thereof, a disengageable connection between these members is provided. In the illustrative embodiment, this connecting means takes the form of a head (Fig. 6) attached to each plunger and formed with a channel Ti to receive the roller 4]. When theplunger is in its.

normal retracted position (Fig. 7), this channel is aligned with a groove 18 formed in the guide bracket 43 which constitutes a track for the roller 4|. As the trough 21 is moved to the i right (Fig. '7) the roller 4| enters the channel in the head to connect the plunger to the trough, the groove and channelbeing flared to facilitate the entry and withdrawal of the roller in the head 11.

In its rearward movement the plunger 60 operates to compress a spring 19 (Fig. 6), which returns the trough 21 to its normal position after a wound bobbin has been discharged. This spring is retained in a bore ll-l in an enlarged portion of the arm 31 provided for this purpose and operates against a movable bracket attached to the base plate 42 and supporting the roller 4|. The plate 42 has a stop lug 8| for engagement with a coacting stop surface 82 on the arm 3'! to prevent the trough from being forced off of the arm by the spring 19.

As previously stated, all operations are performed in timed relationship with each other. In the present instance, the gear 58 is rotated to withdraw the centering slide l3 and a wound bobbin is released from the spindle I2 which falls into the trough 21. Rotation of the gear 58 is also accompanied by the rocking of the shaft EB and the toggle link ll through approximately of displacement. As the latter passes through its point of maximum throw in one direction, arm 75 is rocked about shaft and plunger 69 is moved forward in an idle stroke. Before the toggle link 1| approaches a point of L second maximum thrust in the opposite direction of its rotation, the trough 2! is moved into position before the conveyer l6 and the roller 4| has entered the head 11 on the plunger 60. When the second point of maximum throw is reached, the trough and plunger being thus con-- nected are moved together toward the conveyer and the wound bobbin 6| is pressed onto one of the pins ll to complete the transfer operation.

It will be observed that thecomplete trans ferring operation of the Wound bobbin 6| from the spindle to the conveyer is made without subjecting the filling thereof to contact with any surface that would cause injury to it. Thus it will be noted from Fig. 6that trough 21 is shaped to support the wound bobbin 6| solely by its tip 83 and its head 84. This prevents the filling from touching the interior of the trough at any time. Moreover, movement of the bobbin with the trough does not disturb this condition. Thus, as trough 27 moves toward the conveyer, the end thereof bears against the tip 83 and presses it onto the pin ll without relative movement of trough and bobbin. When the bobbin is firmly positioned on the pin, it is supported in a horizontal position as will presently be described. Consequently, as the trough is retracted and the support of tip 83 is withdrawn, the bobbin is prevented from sagging and the trough is returned without the filling of the bobbin dragging on the bottom surface.

The storage-conveyer mechanism to which filled bobbins are delivered by the foregoing transfer mechanism, will now be described in connection with Figs. 2, l, 6 and 7. In general, this storage-conveyer mechanism provides a means for taking bobbins from the transfer mechanism one at a time and storing a number of them separately for an interval of time. In the present embodiment of the invention, this period of time is provided for by moving the storterval of time required for-ia'bobbin to'make this vertical run preferably provides aatime period of sufficient duration to enable'aisingle operator to attend a numberof' units ormachines, sinceshe can remove the continuously advancing bobbins at any point in their run.

."As illustrate-din the drawings, the storageconveyer heretofore generally designated I6, comprises an endless chain-t whichis' carried overaplurality of 'sprockets.'ii6,=-86 86 and 86 suitably: supported on the -machine frame and drivenjby aratchet drive-SI! (Fig. 2). This chain iS;8.dV 8.IlCd in ste-p-b-y-step fashion and moves the-bobbins deposited on the pins 51- vertically fromthe 'level of that-rough 2'! to the top-of the-machine. .During this run-the bobbins are successively presented for removal.

The chain 35 is made up of a number of links 85 to which are attached at spaced intervals cross-barssill. These bars are fixed to their re" spective links bya pair vof L-shaped brackets il'lbandrigidly support the. pins II. At opposite'ends, the 'bars are'beveled at 88 for reasons which will be developed later. .Eachwbar'also supports a spring clamp 89' (Fig. 6) Which-enga-ges rings an on bobbin head M to hold the bobbin-in placeron the'pin once it isv deposited there.

Each of the pins carriedon-the chain must be guided vertically with respect'to' the trough 2'! andveach should be firmly held while a'bobbin is being pressed onto itespecially during the retraction of the trough TI to avoid injury to the filling as above set forth. Further, after a number of bobbins have been deposited ontoa section of the'ch'ain, it is important that means be provided to prevent that section from bending or sagging and thereby maintain the bobbins in a horizontal position. Such are the functions of aclamping device 9I and coacting guides 92 and Q3 (Fig.6) I

Thedevice QI comprises two spring pressed arms 94 (Fig. 4) pivoted at 95 on a casting 96 fast to the frame of the machine. These arms carry a pair of hardened members 97 which-are notchedwat -lil to engage and hold a shouldered portion -59 of the pins I'I under the action of springs I60. The members Ell are beveled on their lower rear side at Iill and cooperate with the beveled edges 88 of the bars 8'! to hold the chain firmly against the guide 93 which is in the form of an elongated bar. .For coaction with the :chain; this bar has a face I02 providing a track for the chain and the projecting portions of the links act as flanges which guide the chain along this track. For easy movement .of the chainonto the 'bar, a bevel W3 is cut in its face at the lowerend of the bar.

As the chain is advanced vertically, it is further guided and: held by guide 92. This guide (Fig. 7) is fashioned from two channeled sideplates I Q, whose channels I tfiform-tracks in which the cross bars 81 slide. Thesechannels run parallel with the chain and are so dimensioned as to permit free running of the chain andat the same time prevent the turning of the bars 81 about their longitudinal axes under the gravitational torque. of wound bobbins-riding on the pins. The plates IM are separatedtby a space bar I06 which .is rigidly attachedxto bar 93 .as a supportfor: the guide.

a One :of I the important features 0f the iconveyer I 6 T'iS its drive mechanism 9,- which impartsa step-by-step advancing or indexing "movement to the storage chain'85 and indexes the pinscar I ried thereon-into positionwith respect to the trough El. This device isattached to the housing of drive control mechanism 26 (Fig. Hand is operated thereby. Thus a chain index cam Ili mounted on the main cam shaft 2 itrockszan arm I68 toturn a shaft M0, the arm "havinga follower IE9. Keyed to shaft IIQ is anarm III which has an adjustable tension spring IIZ (Fig. 2) attached'thereto that holds cam follower "I09 in contact with cam NW. The arm III isconnected to an arm of a bell crank Ht (Fig.'-.3), loosely mounted on an indexing shaft M4, by means of an adjustable link II5. The-.Other arm of the crank 553 carries a pawl lIfi which' drives a ratchet wheel II'i, said pawl beingiheld in engagement with the wheel by a. spring I I8. The ratchet Wheel II! is keyed to the shaft I'M and-drives the same. As the shaft IItl-is :rotated, the sprocket 86 (one for eachunitl is turned to advance the chain through one inc'rement of movement and this positions onerof the pins to have a filled bobbin pressed ontoit. A spring impelled holding pawl I I9 acting against the ratchet I E? is provided to prevent the weight Of'filld bobbins from driving the chain in the wrong direction. Since the ratchet II'I initiates the movement of the chain as at the same time that the plunger (it) is withdrawing thetrough 2i of the transfer mechanism i8, and further since the timing of these movements are such as to require it, a notch Iii] (Figflllis cut. in the'trough to permit the pins I? to passes the chainis advanced. I

Operating in timed relation with the bobbin transfer mechanism D is a clamping and shearing device I EI (Figs. 7, 8 and 9), whose functions are to clamp'the strand during thedon'ning operation and subsequently to shear it from a wound bobbin which has been released from the winding mechanism onto the transfer device, allas'fully set forth in said copending application.

In the present instance the clamping and shearing elements proper are attached toa horizontal plate. I23 (Figs. '7, 8 and 9) whichis situated'below. and to the rear of chuck I2 and is fixed to the machines frame I25 by a' bracket I25. Carried on the bottom of this plate is a bell crank I26 (Fig. 7) carrying a'pair of blades I2! and; I251. The blade i2? is mounted adjacently to :the plate and its leading edge is rounded so as to clamp the strand between it andthe plate when the blades are moved across a notch I29 in the plate I23 into which the strand is drawn. After the strand is clamped thereby, continued movement forces th blade I28, whose leading edge is sharpened, against a stationary arm I30 to sever the strand.

The movement of the blades I2? and I28 is effected by rocking the bell crank I25 about its pivot IEI against the tension of a spring I32 which holds the same in normal position against a stop I 33. The bell crank in turn is moved by a rack bar I3 supported to reciprocate ina plane parallel to the axis of the bobbin being wound and carrying on its forward end a bracket I35 normally occupying a position adjacent the rear end of the trough. At the end of its extreme rearward movement, a lug I36 on the bracket I35 engages one arm of the bell crank I 26 to operate the clamping and shearing elements as abovedescribed. I

The rack bar I34 is also utilized in drawing the running strand into the shearing device I2l. Thus a pair of wire fingers I31 and I38 attached to the bracket I35 on the rack bar I34 is adapted to snare and retract the strand, which extends from the yarn mass to the wound bobbin dropped in trough 2i and draw it into the shearing device on the retracting stroke of the arm. The finger I3! is straight and is located in front of and above the shearing elements while finger I33 is bent and located below and rearwardly of the finger I 31 so as to pass underneath the blades (Fig. 9) when the arm is retracted.

Since the bar I34 is in its retracted position during the donning operation, bracket I35 offers an excellently positioned mounting for a bobbin guide plate I39 (Fig. 9). This plate prevents a bobbin from shifting rearwardly of the chuck I2 as the bobbins are being shifted to the winding position. The bracket I25 provides a similar mounting for a plate IMJ which is fashioned in the form of an apron beneath the shearing device. Its sloping surface tends to cam the wound bobbins forward as they fall from the spindle and position them in the trough 21 so that their heads will be disposed forwardly of the chain pins on the conveyer IS when the transfer device moves to position them.

It will be apparent that the shearing operation must occur before a wound bobbin, which has been dropped into the trough 21, is moved into position before the conveyer or wastage of yarn will result. Accordingly, the strand is sheared before the arm 25 is moved toward the conveyer and this timing is provided from the central drive control 26 from which the hearing device is operated.

Here, as with the other instrumentalities described, the mechanism is operated by a cam driven by the main cam shaft 2|. This cam is in the form of a "groove I41 (Fig. 2) cut in one face of .a gear Mi (Fig. 1) for receiving a roller follower I42 carried by an arm M3 mounted to turn on a pivot IM. A segment I45 c'arriedon the end of the arm I 42 raises and lowers a rack I46 which rotates a pinion I41 keyed to a shaft I 43. Mounted for rotation with the shaft I48 is a gear I49 which meshes with a rack section I56 of the rack bar I34 to advance and retract the same all in a manner described above.

With the description of the various instrumentalities forming the invention completed, their coordinate action may be now summarized. For such analysis, one winding cycle of one unit will be related and it will be assumed that the previous cycle has ended with a wound bobbin in the chuck I2 and with the chain feed ratchet 90 positioned to take up another tooth.

As the winding operation is completed, the shear cam MI through its associated elements, advances the rack arm I34 to its forward position and similarly, the centering slide cam 62 retracts the centering slide it to release the wound bobbin from the chuck 12 This extends the strand I22 from its source to the trough 2'I intermediate the fingers I31, I38 and the chuck I2 Simultaneously with the withdrawal of the centering slide l3, the toggle II is operative to advance and return the plunger 60 in an idle stroke. Next, the rack bar I34 is retracted and the strand is pulled into the clamping and shearing device I2 I- by the finger I31 where it is sheared and also clamped to position the same across the open mouth of the chuck Ill The carrier arm 25 then advances under the action of the barrel 10 cam 52 to its position illustrated in Fig. 5. This moves the cradle 26 to position an empty bobbin for clamping in the chuck I 2 and the trough 21 into alignment with the conveyer I 6 and into operative relation to the plunger 60. The centering slide I3 is then advanced, and at the same time the plunger 60 is driven forward to press the trough 21 together with its wound bobbin to carry the latter onto one of the pins ll of the conveyer. The forward action of the centering slide forces the running strand together with the empty bobbin into the chuck. To complete the cycle, the plunger 60 is retracted, positioning the roll-er AI in alignment with the groove I8 in the bracket t3, whereupon the arm '25 is returned to its initial position. Retraction of the plunger permits the [trough ZIto be returnedby the spring I9 into a .position clear of the chain. Thereupon the ratchet 90, driven by its cam IIII, advances another pin on the conveyor into position where it is clamped by the clamping device SI. As the cycle is repeated, a number of bobbins are stored on the conveyer and slowly moved over along ivertical run for removal at the will of an operaor. i a
